Aaron Klotz 855f79fad7 cmd/tailscaled, util/winutil: changes to process and token APIs in winutil
This PR changes the internal getTokenInfo function to use generics.
I also removed our own implementations for obtaining a token's user
and primary group in favour of calling the ones now available in
x/sys/windows.

Furthermore, I added two new functions for working with tokens, logon
session IDs, and Terminal Services / RDP session IDs.

I modified our privilege enabling code to allow enabling of multiple
privileges via one single function call.

Finally, I added the ProcessImageName function and updated the code in
tailscaled_windows.go to use that instead of directly calling the
underlying API.

All of these changes will be utilized by subsequent PRs pertaining to
this issue.

Will Norris 9b537f7c97 ipn: remove the preview-webclient node capability
Now that 1.54 has released, and the new web client will be included in
1.56, we can remove the need for the node capability. This means that
all 1.55 unstable builds, and then eventually the 1.56 build, will work
without setting the node capability.

The web client still requires the "webclient" user pref, so this does
NOT mean that the web client will be on by default for all devices.

In corp PR #14970 I updated the installer to set a security mitigation that
always forces system32 to the front of the Windows dynamic linker's search

Unfortunately there are other products out there that, partying like it's
1995, drop their own, older version of wintun.dll into system32. Since we
look there first, we end up loading that old version.

We can fix this by preloading wintun using a fully-qualified path. When
wintun-go then loads wintun, the dynamic linker will hand it the module
that was previously loaded by us.

Brad Fitzpatrick 3d7fb6c21d derp/derphttp: fix race in mesh watcher
The derphttp client automatically reconnects upon failure.

RunWatchConnectionLoop called derphttp.Client.WatchConnectionChanges
once, but that wrapper method called the underlying
derp.Client.WatchConnectionChanges exactly once on derphttp.Client's
currently active connection. If there's a failure, we need to re-subscribe
upon all reconnections.

This removes the derphttp.Client.WatchConnectionChanges method, which
was basically impossible to use correctly, and changes it to be a
boolean field on derphttp.Client alongside MeshKey and IsProber. Then
it moves the call to the underlying derp.Client.WatchConnectionChanges
to derphttp's client connection code, so it's resubscribed on any
reconnect.

Some paranoia is then added to make sure people hold the API right,
not calling derphttp.Client.RunWatchConnectionLoop on an
already-started Client without having set the bool to true. (But still
auto-setting it to true if that's the first method that's been called
on that derphttp.Client, as is commonly the case, and prevents
existing code from breaking)

check step over noise) from the daemon. This switch also allows
us to run the web interface as a long-lived service in environments
where the CLI version is restricted to CGI, allowing us to manage
certain auth state in memory.

Aaron Klotz 95671b71a6 ipn, safesocket: use Windows token in LocalAPI
On Windows, the idiomatic way to check access on a named pipe is for
the server to impersonate the client on its current OS thread, perform
access checks using the client's access token, and then revert the OS
thread's access token back to its true self.

The access token is a better representation of the client's rights than just
a username/userid check, as it represents the client's effective rights
at connection time, which might differ from their normal rights.

This patch updates safesocket to do the aforementioned impersonation,
extract the token handle, and then revert the impersonation. We retain
the token handle for the remaining duration of the connection (the token
continues to be valid even after we have reverted back to self).

Since the token is a property of the connection, I changed ipnauth to wrap
the concrete net.Conn to include the token. I then plumbed that change
through ipnlocal, ipnserver, and localapi as necessary.

I also added a PermitLocalAdmin flag to the localapi Handler which I intend
to use for controlling access to a few new localapi endpoints intended
for configuring auto-update.

Maisem Ali e6ab7d3c14 cmd/testwrapper: parse args better
Previously we were just smushing together args and not trying
to parse the values at all. This resulted in the args to testwrapper
being limited and confusing.

This makes it so that testwrapper parses flags in the exact format as `go test`
command and passes them down in the provided order. It uses tesing.Init to
register flags that `go test` understands, however those are not the only
flags understood by `go test` (such as `-exec`) so we register these separately.

Maisem Ali 4899c2c1f4 cmd/containerboot: revert to using tailscale up
This partially reverts commits a61a9ab087
and 7538f38671 and fully reverts
4823a7e591.

The goal of that commit was to reapply known config whenever the
container restarts. However, that already happens when TS_AUTH_ONCE was
false (the default back then). So we only had to selectively reapply the
config if TS_AUTH_ONCE is true, this does exactly that.

This is a little sad that we have to revert to `tailscale up`, but it
fixes the backwards incompatibility problem.

net/dns/resolver: race UDP and TCP queries (#9544)
Instead of just falling back to making a TCP query to an upstream DNS
server when the UDP query returns a truncated query, also start a TCP
query in parallel with the UDP query after a given race timeout. This
ensures that if the upstream DNS server does not reply over UDP (or if
the response packet is blocked, or there's an error), we can still make
queries if the server replies to TCP queries.

This also adds a new package, util/race, to contain the logic required for
racing two different functions and returning the first non-error answer.

1.50.0 switched containerboot from using `tailscale up`

authkey is now re-applied on every boot by `tailscale login`,
where `tailscale up` would ignore an authkey if already
authenticated.

Though this looks like it is changing the default, in reality
it is setting the default to match what 1.48 and all
prior releases actually implemented.

Brad Fitzpatrick eb9f1db269 cmd/tsconnect/wasm: register netstack.Impl with tsd.System
I missed this in 343c0f1031 and I guess we don't have integration
tests for wasm. But it compiled! :)

Brad Fitzpatrick 343c0f1031 wgengine{,/netstack}: remove AddNetworkMapCallback from Engine interface
It had exactly one user: netstack. Just have LocalBackend notify
netstack when here's a new netmap instead, simplifying the bloated
Engine interface that has grown a bunch of non-Engine-y things.
(plenty of rando stuff remains after this, but it's a start)

Brad Fitzpatrick 7c1ed38ab3 ipn/ipnlocal: fix missing controlknobs.Knobs plumbing
I missed connecting some controlknobs.Knobs pieces in 4e91cf20a8
resulting in that breaking control knobs entirely.

Whoops.

The fix in ipn/ipnlocal (where it makes a new controlclient) but to
atone, I also added integration tests. Those integration tests use
a new "tailscale debug control-knobs" which by itself might be useful
for future debugging.

Brad Fitzpatrick 4e91cf20a8 control/controlknobs, all: add plumbed Knobs type, not global variables
Previously two tsnet nodes in the same process couldn't have disjoint
sets of controlknob settings from control as both would overwrite each
other's global variables.

This plumbs a new controlknobs.Knobs type around everywhere and hangs
the knobs sent by control on that instead.

cmd/testwrapper: fix exit deflake (#9342)
Sometimes `go test` would exit and close its stdout before we started reading
it, and we would return that "file closed" error then forget to os.Exit(1).
Fixed to prefer the go test subprocess error and exit regardless of the type of
error.

Brad Fitzpatrick 0396366aae cmd/testwrapper/flakytest: don't spam stderr in Mark when not under wrapper
If the user's running "go test" by hand, no need to spam stderr with
the sentinel marker. It already calls t.Logf (which only gets output
on actual failure, or verbose mode) which is enough to tell users it's
known flaky. Stderr OTOH always prints out and is distracting to
manual "go test" users.

optional.

Previously, foreground mode only worked in the simple case of `tailscale funnel <port>`.
This PR ensures that whatever you can do in the background can also be
done in the foreground such as setting mount paths or tcp forwarding.

This PR adds a new field to the serve config that can be used to identify which serves are in "foreground mode" and then can also be used to ensure they do not get persisted to disk so that if Tailscaled gets ungracefully shutdown, the reloaded ServeConfig will not have those ports opened.

Marwan Sulaiman a4aa6507fa ipn, ipn/ipnlocal: add session identifier for WatchIPNBus
This PR adds a SessionID field to the ipn.Notify struct so that
ipn buses can identify a session and register deferred clean up
code in the future. The first use case this is for is to be able to
tie foreground serve configs to a specific watch session and ensure
its clean up when a connection is closed.
